It is not about using an encrypted file system, but about encrypted metadata 
when you copy to an external drive or share the file over dropbox etc. 
If the tags, ratings etc. are encrypted strings your metadata would be safe.

You could a share a document not containing any personal information (a third 
party document stored on your hdd), but the comments or tags could contain 
information you do not want to share with others. 


Another question I could not find answered in the wiki: Is semantic information 
also stored in file attributes? (e.g. received from ....), or does semantic 
information still rely on a database?
